Nic, I looked at the peppermint pics on the website and they appear to be a cranwelli x ornata hybrid. Notice the skin protuberences which indicate ornata.
As far as fertile hybrids go, most should back cross with reasonable fertility. The exception would be cornuta hybrids which will be sterile, and will not even hybridize with ornata.
You would be far better off purchasing groups of small frogs and raising them to create your own hybrids. The cranwelli x ornata hybrids are usually avialable. The are sometimes called Orwell horned frogs.
